RESUMO
The present study was designed to determine the effects of puerarin pre-treatment on the pharmacokinetics of the oral anticoagulant agent warfarin and the antiplatelet agent clopidogrel in rats. In the treatment group, rats was gavaged with warfarin or clopidogrel after repeated treatment with puerarin at intraperitoneal doses of 20, 60, or 200 mg·kg(-1) for 7 days, while rats in the control group were administrated only with the same dose warfarin or clopidogrel. Plasma samples were obtained at the prescribed times and analyzed by liquid chromatography tandem mass spectrometry (LC-MS/MS). The results showed that rats treated with puerarin at all the test doses of 20, 60 and 200 mg·kg(-1) were found to affect the pharmacokinetics of warfarin, but not clopidogrel, suggesting a potential herb-drug interaction between puerarin and warfarin.

Phellinus is a kind of rare medicinal fungus that has a variety of physiological activities include anti-cancer, anti-liver fibrosisa, antioxidant and so on. Phellinus contains polysaccharides, steroids, terpenoids, flavonoids, pyrone, furan, alkaloids and other substances. Polysaccharide extracts of phellinus showed obvious antitumor effect and has been a hot research field in recent years. It was also found other extracts of phellinus such as ethyl acetate extract exhibited anticancer activity. Thus, the antitumor effect of different extract, especially the anti-cancer mechanism were discussed in this review.
